[Radiance-general] Glare analysis

[Christopher Rush]

The evalgare software is intended to be used with a 180° fisheye view to capture the whole visible hemisphere.

Regarding the time difference, there seems to be different rendering parameters resulting between the two simulation methods. The Radiance .rif file for the glare image is set to be 512 pixels while the Diva script seems to be up to 1200 pixels tall. You have one indirect bounce in the .rif file, but two (-ab 2) from the Diva script. If you check the model.opt file generated via your .rif file, you could compare them to the -ar, -ad, -aa and other settings in the Diva script and will probably find other rendering parameter differences causing a faster or slower (and less or more precise) rendering of the lighting conditions.

If you view the .pic and .hdr images from each method, does either one look like a realistic representation of your scene? Or do both look a bit simplified with not enough reflections accounted for?
